2021 Sunday Primer Park Overview

The Primer is a serious starter bike at a seriously great price. New for 2021 is the Primer Park model with a park specific geometry and an Odyssey Gyro that is connected to a pro-level Odyssey M2 Trigger lever and pre-cut dual lower cables for better braking and easier maintenance.

Built around a pro-level geometry in a range of top tube sizes, the Primer is spec’d with quality parts like Odyssey Springfield brakes and Path Pro tires. The 2021 Primer also includes a fully sealed rear cassette hub and proven parts like the Sunday Freeze Stem and an FSA Headset.

Frame Geometry

A: Top Tube Length:  20.5″ – Learn what size is right for you here.

This is a short toptube.

Designed for riders who are 5′ 3″ to 5′ 9″

B: Chain Stay Length: 12.7″ – 13” – Learn About Chain Stays Here

This is a pretty short chain stay. Shor chain stays give you the ability to snap the bike around.

C: Head Tube Angle: 75.5° – Learn About Head Tube Angles Here

Steep head tube angles make the bike “snappy” meaning more responsive to fast turns.

A less steep head tube gives you more control.

D: Seat Tube Angle: 71°

E: Bottom Bracket Height: 11.6″

F: Stand over height: 7.5″

This is a low standover. A low standover makes tail whips really easy. Barspins will be harder though because there isn’t much to pinch.

2021 Sunday Primer Park Price

This is a pretty low-quality bike, to be honest. It comes in about $30 cheaper than the 2020 Fit PRK but has no chromoly. I think that $369 is a lot for a bike without any chromoly.

2021 Sunday Primer Park Quality

Sunday’s Primer Park has quality that will hold up to beginner-level riding. This isn’t helpful if you plan on only having one bike as you progress to a higher level of riding. With only hi-tensile steel and single wall rims, this is a lower quality bike.

Highlights

Park Specs

The geometry is very similar to a fully custom park bike. I think that this is super cool because complete park bikes like this are kinda rare. It really does help you focus on park riding when you ride something like this.

Lowlights

Hi-tensile steel/single wall rims

These are weak specs that tend to break or bend over time. If you start sending yourself down big stair sets or casing big ramps.. you will not be having fun on this bike.

Buy if you are learning:

  • tailwhips
  • 180
  • airing quarters
  • 360 taps
  • spines
  • no handers

Don’t buy if you are learning:

  • Freecoaster tricks
  • Grinding hand rails
  • Huge drops
  • 720
  • Flips
  • Big 360

2021 Sunday Primer Park Conclusion

So, the Park edition of the Primer is designed for beginner level riders who want to focus on park. The geometry will make street riding and flow kind of hard. People who run this kind of set up, do really tech park tricks like footjam whips and spins and lip combos. If you are at a mid to high-level of riding… you will need a bike with more quality.
